While Paris was at the top of her fame her trusty sidekick was Kim, but they fought with each other and are now no longer friends. However, Kim’s fame has skyrocketed since and as RadarOnline.com exclusively reported, this has infuriated Paris.

“Kim will always be a sore spot for Paris because she believes that without her Kim wouldn’t have the success she has in her life,” a source close to the situation previously told RadarOnline.com. “Paris thinks Kim wasn’t a loyal friend to her and only used her to gain fame and that she is ungrateful for everything Paris claimed to do for her.”

Despite the fact that Paris’ first album sold only 197,000 copies when it was released in 2006, the hotel heiress “is focusing all of her creative energy into her second album,” a source close to Hilton told RadarOnline.com.
